In recent years, existing solutions for cooling personal computer CPUs have been supplemented by a new product category, factory sealed water cooling loops. These systems, consisting of a water block with an integrated pump, a fan and a radiator, perform well compared to the air cooling solutions but are less effective than larger, custom-built water cooling systems.This project aims to explore the most important aspects of a factory sealed system and to identify possible cost-effective enhancements of the performance.The most significant differences between the different groups of water cooling loops are the block design and the pumping power. The performance of both categories is also largely dependent on the fan power, but increasing fan power has a large negative impact on the noise level.Both radiator size and fan model choice appear, in tests, to be relatively unimportant, presuming that the noise level is kept constant. The position and direction of the fan, however, has significant impact on both the temperature and the sound level.Water blocks can be designed in several different ways, both regarding the heatsink design and the flow direction. In simulation, flow with the inlet centered above the heatsink result in considerably lower pressure drop and slightly higher temperatures than flow through the block, for heatsinks with fin arrays.Creating a competitive product in this product segment certainly seems possible, as there are performance-increasing changes to be made that seemingly has little impact on the production cost.

The use of Power Line Communication, PLC, as a communication solution for Automated Meter Reading, AMR, is popular by utilities in Sweden and other parts of the world due to demands of accurate and fast meter reading. However the use of the electrical grid as a communication medium is complex and sometimes problematic. This report handles some of the issues and problems that are important to understand when using the grid as a communications medium. Focus is mainly on investigating high frequency distortion in the Kristianstad power grid own by C4energi caused by a frequency converter. Measurements on site are done to investigate signal damping in the grid, different configurations for the frequency converter and signal strength of the PLC-system.

Numerous studies raise the topic of highly educated immigrants whose education and list of qualifications devalue in the context of the Swedish labour market. However, little is known of those with foreign background who enter into higher education in Sweden. Our study attempts to shed some light onto the value of higher education relative to that of a person?s ethnic background. The background material features nine in-depth interviews of foreign background academics, as well as data extracted from an extensive survey study previously carried out at Växjö University. Initially, the quantitative data showed that students with foreign background, including Swedish-born children of immigrants, had not managed to find qualified work upon completion of studies to the same extent as their Swedish background counterparts.

The purpose of this study is to compare the representation of criminals in the Swedish television show ?Efterlyst? regarding ethnical background between the year 1998 and the year 2006. The aim is to determine if and how the representation of ethnicity have changed over the examined years. We have then examined 13 shows from each year and categorized the criminals by ethnicity, type of crime and length of each segment. We have come to a conclusion that the show has a noticeable overrepresentation of criminals with non-Swedish ethnical background.

The purpose of this study was to, using statistical analysis, investigate to what extent families of a different cultural background have participated in family therapy and other family treatment programs at Familjeenheten in Lund. With questions regarding the goals of treatment, and the importance of cultural competence in the treatment process we have let two unit managers comment on the statistics. The population of the study is too small to allow general conclusions to be drawn, however, we have been able to ascertain that families of a different background are over-represented relative to their percentage of Lund´s population. Familjeenheten has no statistical record of ethnicity and the interviewed persons express no certain importance in the families´ cultural origins. They express no need to develop special treatment methods that take the clients´ cultural background in regard as they feel that so many of family issues are universal.

Title: How do music students with different genre backgrounds perceive the same music? In this paper I report a study about how music students with different genre background perceive the same music. I let twentyone classical music upper secondary school pupils and twentyone rock music upper secondary school pupils listen to ten short music pieces of different character and styles. While listening, they were asked to answer four questions about which instruments they could perceive, what they could tell about pulse, rhythm and beat in the music, which component they thought was the most important in the piece and what word they thought best described the feeling of the piece. All four questions had to be answered for each piece of music to facilitate analysis of differences connected to genre background in those answers.

Teorier inom Kognitiv hörselvetenskap beskriver hur uppfattning av tal beror på två olika typer av processer. Bottom-up processer associeras med akustiska och fonetiska egenskaper hos en inkommande signal och top-down processer associeras med lexikala, syntaktiska, semantiska samt kontextuella egenskaper. Förmågan att utnyttja top-down processer tros bero på kapaciteten hos arbetsminnet. För att undersöka en skillnad mellan bottom-up och top-down samt deras förhållande till arbetsminnet har ett Speech-in-Noise (SIN) test utformats och genomförts på 15 försöksdeltagare. Testet undersöker skillnader i tröskelvärden för att identifiera ett enstavigt ord i ett uppåtgående förhållande till stationärt brus, mot tröskelvärden för att identifiera ett enstavigt ord i stationärt brus med hjälp att top-down stöd.

Volvo Human Monitoring (VHM) is an ongoing project at Volvo Cars where they measure, amongst other parameters, inhalation and exhalation through a device called Respiratory Inductance Plethysmograph (RIP), on drivers. RIP measures changes in the cross-sectional area of the chest and abdomen. When the driver is in motion, such as when she is turning the vehicle, the cross-sectional area changes and noise in the RIP signal may arise.The noise results in a large number of manual adjustments in the analysis of the RIP signal, which is very time consuming and the validity of the device for measuring inhalation and exhalation is questioned.The purpose of this study was to improve the efficiency of the analysis of the RIP signal. The goal was to create a new data processing tool in Matlab that automatically detects inhalation and exhalation from a RIP signal with higher validity compared to the previous data processing tool.In this study, nine tests were performed on drivers while they were driving in different scenarios such as highway, country road and in city traffic. Inhalation and exhalation was measured using a RIP, a pneumotachograph with a tightly sealed facemask and a thermocouple placed between the nose and mouth, which was used as reference to the RIP.The result of this study was a data processing tool that automatically detects inhalation and exhalation with higher validity compared to the previous data processing tool.

The aim of the study was to examine the retinal ON- and OFF-pathways of the canine electroretinogram (ERG). The ON- and OFF-pathways are used to distinguish objects from their backgrounds. A dark object is discernible from a lighter background using the OFFpathway and the ON-pathway is used to descry a light object upon a darker background. This study shows that the dog ERG has both ON- and OFF-responses and that these responses can be separated by prolonging the flash duration over 50 ms. The dog OFF-response waveform was more similar to the cat OFF-response than the human OFF-response (Frishman, 2006; Zrenner and Gouras, 1979). In this study six female three-year-old Beagle dogs were included. Both background and flash stimuli were provided by LEDs (light emitting diodes) with a wavelength of 470 nm, a wavelength that is absorbed almost as effectively by the canine M/L-cones as by the S-cones. These stimuli gave ERGs with both ON- and OFF-responses.

The North-American sociologist Michael Lipsky has characterized social workers as street-level bureaucrats with a substantial discretion in the relationship between the welfare state and its citizens. Within Lipsky´s theoretical framework social workers appear as a powerful group that socializes the citizens to uphold certain expectations towards the welfare state and its (re)distributional programs. From this point of view, it is important to learn more about social workers and the attitudes they express towards the welfare state. The aim of this study is to analyze how the welfare-political attitudes of future social workers are affected by their social background (e.g. class background and ancestral homeland).

Young women with immigrant background are generally looked upon as victims of patriarchal structures and cultural determinism.The purpose of this bachelor thesis was therefore to have a salutogen perspective. We investigated how young women with a transcultural background are affected by and how they use their experiences from different backgrounds in their creating of identity.We based our essay on qualitative interviews and current research on the subjects of multi culture, identity and youth. The interviewees were seven young women with experience of multi cultural background and performing different kind of artistic activity.The theory and empirical material combined and compared resulted in three themes: affinity, cultural hybridization, and salutogen factors.We saw that for those young women affinity functioned as a basis for creating identity and that their double background enriches them in several aspects. The three major salutogen factors that the interviewees had in common, and we emphasize, are their struggle, open mind and awareness of freedom.The global youth culture has a great impact upon the young women and to some extent we could recognize cultural hybridization. We consider this neglected subject urgent and very relevant for social work in the multi cultural society of Sweden..
